Katy Perry's 2014 tour plans will see her pair up with two artists who graced the stage during her "We Can Survive" album release concert party at the Hollywood Bowl in October of 2013.

Kacey Musgraves, whose bonding with Perry for the event led to joint songwriting sessions, will take on tour support duties for the middle third of the summer North American leg of the tour, routing through northern U.S. and Canadian arenas through most of August.

Tegan and Sara, fellow veterans of that same Hollywood Bowl show the week of Perry's "Prism" release, pick up the latter third of the tour, covering the west coast and dipping into the south.

Pre-sale tickets for the entire tour go on this this morning (1/21) at 10am local time for Citibank card holders. A Facebook presale will follow on Thursday (1/23). General ticket sales will follow the succession of advance sales.
